Summary

There are three components to this study: a Field Trial, a Shift Worker Survey, and Focus Groups. The Investigators will study the effectiveness, feasibility, and acceptability of an 8-h sleep intervention in older night workers in an operational environment. The overall goal of the Field Trial is to minimize sleep deficiency and negative outcomes resulting from that, including sleepiness and performance impairments during night shift work. The Shift Worker Survey is designed to understand some of the demographic and operational factors that enable or inhibit the ability of individual shift workers to adopt this intervention. The Focus Groups are designed to glean in-depth information from older shift workers who indicate that they are unable or unwilling to adopt an 8-h sleep timing intervention. Understanding these factors will assist in refining and targeting the intervention to those individuals who will be most likely to benefit from the intervention sleep timing strategy.
